\begin{abstract}
In this experiment we studied a very important physical effect by measuring the
dependence of a quantity $V$ of the quantity $X$ for two different sample
temperatures.  Our experimental measurements confirmed the quadratic dependence
$V = kX^2$ predicted by Someone's first law. The value of the mystery parameter
$k = 15.4\pm 0.5$~s was extracted from the fit. We found that this value is
20\% below theoretically predicted $k_{theory}=17.34$~s. We attribute this
discrepancy to low efficiency of our $V$-detector.

\section{Theory overview}
Here give a brief summary of the physical effect of interest and provide
necessary equations. Here is how you insert an equation~\ref{equ:aperp}:
\begin{equation} \label{equ:aperp}
u(\lambda,T)=\frac{8\pi hc\lambda^{-5}}{e^{hc/\lambda kT}-1},
\end{equation}
where T is temperature in Kelvin, c is the speed of light, etc. Don't forget to
explain what each variable in the equation mean, when you introduce it for the
first time!

\subsection{Error analysis}
Note: this section can be integrated with the previous one as long as you
address the issue. Here explain how you determine uncertainties for different
measured values. Suppose that in the experiment you make a series of
measurements of a resistance of the wire $R$ for different applied voltages
$V$, then you calculate the temperature from the resistance using a known
equation and make a plot  temperature vs. voltage squared. Again suppose that
this dependence is expected to be linear, and the proportionality coefficient
is extracted from the graph. Then what you need to explain is that for the
resistance and the voltage the uncertainties are instrumental (since each
measurements in done only once), and they are $\dots$. Then give an equation
for calculating the uncertainty of the temperature from the resistance
uncertainty. Finally explain how the uncertainty of the slop of the graph was
found (computer fitting, graphical method, \emph{etc}.)

If in the process of data analysis you found any noticeable systematic
error(s), you have to explain them in this section of the report.

\section{Experimental setup and procedures}
Give a schematic of the experimental setup(s) used in the experiment. Here I
need to include a figure~\ref{samplesetup}:
\begin{figure}[h]
\begin{center}\label{samplesetup}
\epsfig{file=setup6.eps, width=0.7\columnwidth}
\end{center}
\caption{Every figure MUST have a caption. \emph{Original captions for this
figure}: (a) Experimental apparatus. (b) Energy levels and applied fields
  ($\Omega_P$, $\Omega_D$) for \emph{N}-resonances on the $D_1$ line
  of $^{87}$Rb. $\nu_0$ is the ground electronic state hyperfine
  splitting and $\Delta$ is the detuning of the probe field from the
  $F=2\rightarrow F^\prime=1,2$ resonance.}
\end{figure}
Don't forget to list all important steps in your experimental procedure!

\section{Experimental data and the data analysis}

In this section you will need to show your experimental results. Use tables and
graphs when it is possible. Table ~\ref{tbl:bins} is an example.

It is also recommended to plot the data graphically to efficiently illustrate
any points of discussion. For example, it is easy to conclude that the
experiment and theory match each other rather will if you look at
Fig.~\ref{samplefigure}
\begin{figure}[h]
\begin{center}\label{samplefigure}
\epsfig{file=fig6_new.eps, width=0.7\columnwidth}
\end{center}
\caption{Every figure MUST have a caption. \emph{Original captions for this
figure}: The dependence of the \emph{N}-resonance frequency on the total
   laser power in the cells with the 25 Torr Ne-Ar mixture
   (diamonds) and with 40 Torr of Ne (triangles). Theoretically calculated
   curves
   are shown as solid lines. The probe
   field is tuned to the $F=2\rightarrow F^\prime=1$ transition of
   ${}^{87}$Rb.  }
